LPI Linux Certification in a Nutshell, 2nd Edition

Objective 1: Install and Configure X11

Most Linux distributions install and automatically configure XFree86, freeing users from much of its installation and configuration. However, Exam 101 requires specific knowledge of some of the underpinnings of X configuration.

Warning

Be careful about installing an X server on a system that already has X installed. A backup should be made prior to the installation.

This outcome is possible partly due to cooperation by manufacturers through public release of graphics device documentation and driver software, and partly due to the tenacity of the XFree86 developers. Fortunately, many manufacturers who were historically uninterested in offering technical information to the XFree86 project have become cooperative. The result is that most recent video hardware is well-supported by XFree86.

Supported video hardware

To avoid problems, it is important to verify XFree86 compatibility with your hardware prior to installation. At the very least, you should be aware of these items:

Your XFree86 version

As with any software, improvements in XFree86 are made over time, particularly in support for hardware devices. You should choose a version of XFree86 that offers a good balance between the video support and stability you require. To determine the version of X you're running, simply issue the following command:

$ /usr/X11R6/bin/X -version XFree86 ...
